The production of the Aszú wine (wine of tears) is a meticulous process, which requires great patience and extensive know-how. It is only possible in good vintages, when nature brings rain at the end of the summer and sun and wind in early autumn, which are the essential conditions for the process for noble berries to from. The berries swollen due to the humidity split and the "Botrytis cinérea" establishes in its skin and creates the noble rot. The same formulas are used to make the wines as have been used for hundreds of years.

Vega Sicilia also owns the Oremus Tokaj winery in Hungary . It was on this site that the first Tokaj Aszu was produced in 1631 and Vega Sicilia continues the century old traditions of making the “Wine of kings; King of wines” as this wine was called by Louis XIV.
